To treat wrist ligament pain, it is best to take over-the-counter pain relievers such as naproxen, ibuprofen and acetaminophen, according to MedlinePlus. When taking these medications, it is important to follow all directions and to not take more than the bottle recommends.
Other ways to treat a wrist sprain causing ligament pain include resting and icing the wrist, explains MedlinePlus. The individual should stop activities that cause pain and splint the wrist if necessary. Icing the wrist for 20 minutes two to three times a day is also helpful, and it's important to wrap the ice pack in a cloth to prevent injury before placing it on the skin.
After a couple of days of rest, the individual should start moving the wrist again by doing exercises such as the ball drill, states MedlinePlus. To do the ball drill, the person should keep her palm up, place a rubber ball in the hand, and then grab it with the fingers. The wrist and hand must stay still as the person gently closes the hand around the ball for 30 seconds and then releases it. It is best to do this about 20 times, two times a day.
There are also exercises that help to increase movement and flexibility in the wrist, claims MedlinePlus. To do this, a person should heat her wrist with a warm cloth or heating pad for about 10 minutes. When the wrist is warm, she should hold the hand flat, grab the fingers with the opposite hand, and gently pull the fingers back toward the wrist. It is best to hold this for 30 seconds and to repeat it five times a day.
